Abstract

A medical appliance for plugging a hole in a nasal septum that includes a central member that has an irregular cross section where its major axis is longer than its minor axis and where the appliance is sized such that the length of the central portion major axis is the same or slightly shorter than a major axis of an irregularly shaped nasal septum hole, and with opposing disks secured across the opposite central member opposite ends that each have a like diameter that is greater than the length of the nasal septum hole major axis. The medical appliance is formed as a single unit from a flexible material to human body compatible material where at least one of the disks can be folded upon itself and will return to its original shape when released.

Claims

exact text as granted — not AI-modified
I claim: 
     
       1. A medical appliance for plugging a hole formed through a human patient's nasal septum comprising, a straight central portion of a length to extend through and is for disposition within a nasal septum hole, said central portion having a longer major axis than its minor axis, with the length of said major axis selected to fit within a longest axis of said nasal septum hole and said central portion is greater than the shortest axis of said nasal septum hole appliance for avoiding appliance rotation; a pair of disks that are each of a greater diameter than the central portion major axis, and with each said disk secured across a central portion opposite end; and said central portion and disks are formed as a single unit from a human body compatible, flexible material. 
     
     
       2. A medical appliance as recited in claim 1, wherein the central portion major axis is slightly less than the longest axis of the nasal septum hole; and the disks have the same diameter that is larger than the longest axis of said nasal septum hole, and said disks opposing surfaces are arranged to abut against opposite sides of said nasal septum, around said septum hole edge. 
     
     
       3. A medical appliance as recited in claim 1, wherein the central portion and disks are formed as a single unit from silicone rubber.
